My recommendation for 5" 1911s that will see mostly 230gr loads is conventionally rated 16# recoil springs.
Throughout my experience I still find them to be the overall best rate and poundage in a 5" gun if for no other reason than the guns are more "shootable" in my hands... but there are other variables an reasons as well. I don’t think 18.5# springs are a bad thing just that they are not needed in a 5” gun. Variable rate springs, in theory at least, let the gun unlock a bit easier by storing their energy progressively and loading up most of the energy as the gun gets further out of battery. At the end the weight rates are the same and the springs are storing the same amount of energy... one just stored it in even increments while the other did it on a curve, so to speak. In the end either will work in your gun but one may “feel” better than the other. |

Ditto.
I run a 14# conventional (or "straight") spring in my 5" 1911 in .45 ACP. The reason so light? The more the recoil spring "weighs" the more muzzle flip you will get. Reducing the spring weight will reduce the amount. However, that doesn't mean you get crazy and run REALLY low rates (for instance on my Open pistol I run a 9# and my Limited pistol carries a 12#). The "correct" spring for me is based on reliability and then feel. Try a couple out, see what works the gun best, then what feels right. As long as the spring doesn't compress past it's full compression (i.e. "slams" into the frame) during cycling, it won't damage anything. And, let's face it....springs are cheap. SPC Richard A.
